Warriors: Golden State played its worst game of the season, losing at Utah 129-99 on Tuesday night. The only Warriors who played well were Klay Thompson, who scored 27 points, and center JaVale McGee, who showed some life off the bench with 14 points on 7-for-8 shooting in 16:08.Kings: Won at New Orleans 114-103 on Tuesday night to conclude its six-game, 12-day trip through Memphis, Charlotte, Orlando, Miami, San Antonio and New Orleans with a 3-3 record. Veteran Zach Randolph had 26 points and 12 rebounds. Center Kosta Koufos had 17 points and a career-high 17 rebounds.

The Kings lead the season series 1-0. … On Nov. 27, playing without Stephen Curry and Kevin Durant, the Warriors found the going tough down the stretch without their two leading scorers as Sacramento pulled out a 110-106 victory at Oracle Arena. The Kings got themselves into the game with a 13-0 run spanning the third and fourth quarters that turned an 82-74 Golden State advantage into an 87-82 lead. Klay Thompson scored 21 points for the Warriors but was only 7 for 20 from the field.

The Warriors have lost consecutive road games (at Houston on Jan. 20 and Utah on Tuesday) for the first time since last March 10 and 11 when they were defeated at Minnesota and San Antonio during that brutal run of eight games in eight cities in 13 days. That was the stretch that caused Steve Kerr to rest his starters for that nationally televised showdown against the Spurs.

On Tuesday, the Jazz beat the Warriors in every way imaginable. Utah scored 58 points in the paint and 42 points on 3-pointers. That’s 100 points for a team that entered Tuesday averaging 101.4 total points per game.

Kings coach Dave Joerger might not be on the bench tonight after suffering a dizzy spell and light-headedness during Sunday’s game at San Antonio. While shouting from the sideline, Joerger went down to one knee. He returned to Sacramento on Monday, was examined by doctors and cleared to return during this Kings homestand. If Joerger isn’t ready, assistant Elston Turner will coach the team.

Against Utah, the Warriors gave up a 60-point first half for the sixth time in seven games. And the Jazz did it with rookie sensation Donovan Mitchell only playing 8:59 in the half because he collected three fouls in the first quarter. In those seven games, Golden State trailed at halftime five times — 64-57 at Cleveland, 66-63 at Chicago, 65-58 at Houston, 54-50 vs. Boston and 69-56 at Utah. Despite their defense, the Warriors led vs. New York 68-60 and vs. Minnesota 74-62.

Warriors rookie Jordan Bell has missed the past five games because of inflammation in his left ankle. He will be re-evaluated today but won’t play tonight. Shaun Livingston will miss the game for personal reasons. Kings center Willie Cauley-Stein, who missed the past two games after suffering a bone contusion in his right knee on Jan. 25 at Miami, might be ready to return.

Joe Ingles and Ricky Rubio usually wouldn’t be high on the list of Jazz threats. That honor would go to Mitchell or Rudy Gobert. But Ingles and Rubio were the prime culprits who killed the Warriors on Tuesday. Ingles hit 5 of 7 3-pointers in the first half, mostly because Defensive Player of the Year candidate Durant chose to leave him open at the arc. Ingles finished with 20 points. Rubio abused Curry on drives and jumpers and had 23 points on a surprising 9-for-16 shooting night, including two 3-pointers.

How young are these Kings? In their past three games, they have started three rookies: Bogdan Bogdanovic, De’Aaron Fox and Justin Jackson. Bogdanovic has been the most steady of the trio so far, averaging 11.1 points on 47.3-percent shooting from the field and 39.1 percent from 3-point range. He is 25 years old and played professionally in the EuroLeague for four seasons. Fox is a quick, gutsy point guard who averages 11.0 points but needs to work on his outside shot. Jackson doesn’t score a lot, but has shot 60.9 percent in his last four games.

With the score 94-76 with 3:49 left in the third quarter at Utah, Omri Casspi checked in for the Warriors for his first action of the night. Fifteen seconds later, he touched the ball for the first time and threw it away to Ingles. Eight seconds later, on his second touch, he threw the ball to Alec Burks, who passed to Jonas Jerebko for a layup. Steve Kerr immediately called a timeout.

McGee, who hadn’t played any meaningful minutes since Jan. 6 at the Los Angeles Clippers, brought some energy Tuesday night that was missing from virtually all of his teammates. In addition to his 14 points (which equaled Curry, by the way), he also had four rebounds, two blocked shots and was active at both ends of the court.

For the second game in a row, the Warriors allowed their opponent to shoot 50 percent from 3-point range. Coincidentally, Boston and Utah were each 14 for 28 against Golden State.
